J-Fall 2015 Speaker Rene Boere, Pascal Snippen & Arjen Wassink – Continuous Delivery

Deze sessie is een verdieping van de keynote en doet uit de doeken hoe wij ons cluster ingericht hebben, inclusief de technische details. Met live demo’s tonen wij hoe principes en technieken werken. Zo zul je zien hoe wij in staat zijn met Git, Bamboo, Docker en Marathon, geautomatiseerd microservices uit te rollen op ons Mesos […]

J-Fall 2015 Speaker Rene Boere & Pascal Snippen – Pushing the limits of Continuous Delivery

Containers, cloud platformen, Service Discovery en Continuous Delivery zijn technologieën die zich momenteel razendsnel ontwikkelen. We passen allemaal al jaren Continuous Integration gecombineerd met unittesten toe in onze projecten. In deze sessie geeft Quintor haar visie hoe we Continuous Integration de komende jaren zien evolueren naar een Continuous Delivery omgeving op Web-scale formaat, gebruikmakend van […]

J-Fall 2016 Speaker Tom Eugelink – One application to rule them all

Wouldn’t it be nice if we could write a mobile app and a desktop app with a single code base. Yes, of course there are HTML based solutions, and they work as well, but maybe you also find developing in HTML, CSS and JavaScript just frustrating as I do. I want to work in an […]

J-Fall 2016 Speaker Pascal Snippen & Rene Boere – Quintor Keynote: Mindblowing: 40+ node PI cluster

Met een Raspberry PI kan alles toch? Dat dachten wij ook. Dus besloten we het grootste Java gebaseerd overheids IT project te porten naar een 40+ node PI cluster. Dit is geen simpele demo applicatie maar deze applicatie wordt gebruikt door meer dan 1 miljoen gebruikers en heeft de gebruikelijke hardware en software requirements dat […]

J-Fall 2016 Speaker Rik van de Ven – A/B testing in the secure banking environment of ING

This talk will introduce ING’s Experiments API. Most A/B testing solutions don’t really fit a secure banking environment. There are also some problems in tools manipulating applications without the applications owners in a DevOps world. ING needed a solution for doing A/B tests in a DevOps world without introducing security risks. We have developed our […]

J-Fall 2017 Speaker Xavier Dupré – Democratization of AI: from researchers to any user

Machine learning somehow became one magic wand able to solve many things. It can be seen as a way to automate an existing pipeline which became very time consuming, it could also be seen as a way to process information we could not handle so far such as images or videos. We usually forget it […]

J-Fall 2015 Speaker Nigel Harniman – Speed up software delivery (Docker- Continuous Delivery)

You’re building applications which have dependencies on configuration files, the operating system and its configuration. Why manage these baselines separately? Why not bundle them into a docker image and manage at the macro level. How do you create this image? How do you track changes to any of the inputs? How do you ensure that […]

J-Fall 2014 Speaker Roy van Rijn – Kill the mutants and test your tests

Quis custodiet ipsos custodes? Better known as: *Who watches the watchmen?* We are all writing tests, doing TDD, BDD. We measure the quality of the tests with line coverage or (even better) branch coverage. This gives you a false sense of security. I’ve seen projects with tests which have 100% branch coverage but not a […]

Full title: J-Fall 2019: Nathan Perdijk – GraalVM in practice at the Dutch National Police: running R from Scala in a Microservice architecture. A lot of the best Data Science is done in R, but getting R to run as a streaming application in a complex environment using only Open Source tooling is an absolute […]
